Leave 1 tsp. of dal aside and grind the rest with the green chilies and ginger.
Add the whole (unground) dal.
Add the soda bi-carb, turmeric powder, and salt, mix well.
Spread a little mixture at a time in a thali (flat metal plate with low rim) and steam to make dhoklas. Repeat for the remaining mixture.
Cool and crumble.
Add the sugar, lemon juice, and a little salt and mix well.
Heat the oil in a vessel and add the mustard seeds. When they stop popping, add the garlic, fry for a few seconds, add the asafoetida and fry again for a few seconds.
Pour this mixture on top of the crumbled dhoklas.
Decorate with chopped coriander, grated coconut, pomegranate and serve.
